The synthesis of protected forms of two amino-sugars, talosamine 1 and allosamine 2, is described; the syn, syn stereochemistry at C-2, C-3 and C-4 was controlled by the use of a hydrogen-bonding directed dihydroxylation reaction using stoichiometric and catalytic OsO4; proof of the relative stereochemistry of the allosamine series was obtained through an X-ray crystal structure of a protected derivative.
描述了两种氨基糖(塔洛胺 1 和别洛胺 2)的保护形式的合成; C-2、C-3和C-4处的syn、syn立体化学通过使用化学计量和催化OsO4的氢键定向二羟基化反应来控制;通过受保护衍生物的 X 射线晶体结构获得了别糖胺系列的相对立体化学证据。
